UNITED STATES FREDERICK BURG-DORE, OF ELYRIA, HIO.

f sLIoING on GRATING MACHINE.

Application 'filed June 21, 1920. Serial No. 390,399.

T0 all whom t may concern:

Be it known that I, FREDERICK BURGDORF, a citizen of the United States, residing at Elyria, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Slicing or Grating Machines, of which the following is a full, clear, concise, and exact description, such as will ena'ble others skilled in the art to which it appertains to make and use'the same.

My invention relates to slicing or grating machines; more particularly it relates to that type of machine of the above character used mainly for slicing or grating vegetables.

Among the obj ects of my invention are the following:

To provide a slicing or grating machine of the rotary type of special construction; to provide a slicing drum of special construction; to provide a frame for operating a slicingdrum orya grating drum; to provide a frame of the above character for driving a slicing or a grating drum, and in combination with said drums, of mechanical means for removing the sliced or grated ma.- terial; and to provide other details of construction tending to increase the efficiency and serviceability of a slicing or grating machine.

To accomplislrthe foregoing and other useful ends, my invention comprises means hereinafter more particularly set forth and claimed.

Referring to the drawings, Figure 1 is a. side elevation of the machine showing the slicing drum in position. Figure 2 shows the grating drum and Figure 3 shows the device for removing the sliced or grated material.

In Figure 1, the main frame 2 of the machine is shown as consisting of a standard provided with a suitable clamp bracket formed integral at the lower end having a clamp screw extending through the lower portion thereof so that the machine may be securely fastened in any suitable locality when it is Vdesired to operate the same. On the upper end of the frame is provided an integral hopper 3, provided with a hd't, integral with which there is formed a cylindrical collar 5 projecting into the hopper. Near the central portion of the frame there is 'a bearing 6 through which a shaft 7 passes. This shaft is held in position be.

tween the collars 8 and 9. On the left of the shaft there is provided a suitable crank y prevented from rotating by the pin 12 and at the same time hold in position. In my arrangement, I provide an auxiliary spider 141-, having a collar arrangement 15, which receives the front end of thedrum 13. It will be seenV that the threaded end ofthe shaft 7 extends through the hub 16 ofthe spider 14 and that the' nut 17 may be screwed on the end of the shaft 7, to hold the spider in position. l

In setting' up the machine, it will be understood that the rake device 18 shown in F `igure 2 isslipped into position inside of the drum and over the shaft 7 before the spider 14k is put in place, as indicated in Figure 1.

Thenever the operator desires to withdraw` any of the material that has accumulated within the cylinder, he merely pulls the right-hand terminal of the hub 19 and draws the rake to the right, which, ofcourse, has l the effect of removing any material that may have accumulated inside.

I have shown in Figure 2 the grating drum. This can be substituted forr the slicing drum shown in Figure 1, in which case the machine may be used as a grater.

I wish it to be understood that although I have shown the cutting drum and` theA gratingdrum, plane cylinders, they may be conical in shape. In such case, the narrow head may b`e arranged to engage the spider 11 and the larger head may be engaged by the spider 15, or vice versa. In either case the spiders will have to be made of different sizes. The spider that is to engage the smaller head will have to be of smaller diameter than ythe spider that is toengage the larger head. Under certain conditions it would be preferable to have the smaller head of the conical cylinder toward the rear and the larger toward the front. With this arrangement the material would be automati cally ejected from the machine and in that case the rake 19 will be unnecessary. y I claim the following as my invention:` 1. In a slicing machine,V a frame standard, a rotatable drum mountedto said frame', a hopper located over a cutting drum and an auxiliary hopper Within said first hopper, Iand pivoted on said first hopper.

2. In a Vegetable slicing machine, a cuttingjr drum 0n a, rotatable shaft, a shuttle rake siida'bly mounted on the shaft in said drum whereby it may be operated by hand to remove the eut vegetable `from the bottom side of the drum, e crank on one end of the Shaft, n thread on the other end of the shaft, a. spider mounted on said shaft 'for supporting said drum, and a thumb screw on said shaft for screwing Said spider in position.

In Witness whereof, I have hereunto` signed my name this 18th day of June, 1920.

FREDERICK BURGDORF.
